Gowanda’s SMRF1812-222J is a high-quality, molded unshielded inductor designed for demanding applications, featuring a compact size of 4.064 × 3 × 2.9 mm and weighing just 0.15 g. This component is part of the SMRF1812 series and is suitable for surface mount technology (SMT) applications, particularly in COTS+ grade environments. It offers an inductance of 22 µH with a low DCR of 3.2 Ω and a current rating of 0.25 A DC. The inductor operates efficiently across a frequency range, with a self-resonant frequency (SRF) of 13 MHz and a test frequency of 2.5 MHz, ensuring a minimum Q factor of 50. It is built with a ferrite core and features a Pb termination type with a Sn63Pb37 finish. The component is designed to withstand extreme temperatures from -55°C to +125°C and is rated MSL 1 for moisture sensitivity. Packaged in tape and reel (T&R) format, it is also fungal inert, making it a reliable choice for various electronic applications.
